I've recently been for a remap on my A3 1.8T Engine code AGU. When it was at the company (R-Tech), they noticed it had a faulty water temperature sensor before remapping. They remapped it anyway, but obviously advised that I had it replaced.
Yesterday I got it back from my local garage. It's had a new water temp sensor fitted, but it feels slightly 'weaker' than before. I can't tell whether it's the humid weather we've had in England the past few days, my imagination or it is actually slower (or a mixture haha)
What I'm hoping you guys will know is whether or not the new water temp sensor is regulating differently to the faulty one that was on before, therefore affecting the car's performance? Obviously the remap was installed when the car had the faulty sensor, and now a new one has been fitted, would it have a negative affect on the remap, or perhaps mean the remap won't work as well with the new sensor as it did with the old faulty sensor?
